Study Notes
Overview of Pelvic Support Structures
- Pelvic diaphragm functions as a supportive structure, compared to a ship in the berth.
- Ligaments and fascia serve as key support systems, analogous to ropes maintaining tension and stability.
Connective Tissue and Endopelvic Fascia
- The endopelvic fascia, composed of collagen and elastic fibers, connects pelvic organs to the pelvic walls and floor.
- Acts as a packing material in the pelvis, adapting during development to provide support.
- Distinct membranes and discrete ligaments cover the pelvic walls, enhancing structural integrity.
Ligamentous and Membranous Support
- Key ligaments include Pubovesical and Pubocervical ligaments, providing structure to the bladder and urethra.
- Urethrovaginal fascia supports the anterior vaginal wall, while the Rectovaginal fascia supports the rectum.
- Uterosacral ligaments aid in maintaining the anteverted position of the uterus.
Uterine Positioning
- Anteversion: Anterior tilt of the uterine cervix relative to the vagina.
- Anteflexion: Anterior tilt of the uterine body in relation to the cervix.
- Variations of retroversion and retroflexion also exist.
Delancey’s Classification of Connective Tissue Support
- Level 1: Supports cervix and upper vagina; includes Cardinal and Uterosacral ligaments.
- Weakness results in utero-vaginal prolapse.
- Level 2: Provides support to the middle vagina; includes Endopelvic fascia and Rectovaginal septum.
- Weakness leads to anterior (Cystocele) and posterior (Rectocele) vaginal prolapses.
- Level 3: Supports the lowest part of the vagina; involves the Perineal body and membranes.
- Weakness can cause anterior and posterior vaginal wall prolapses.
Types of Vaginal Prolapses
- Urethrocoele: Prolapse of the urethra in the anterior wall.
- Cystocoele: Prolapse of the bladder in the anterior wall.
- Rectocoele: Prolapse of the rectum in the posterior wall.
- Enterocoele: Prolapse involving the intestine.
- Uterovaginal prolapse: Involves all aspects of urogenital prolapse.
Broad Ligament and Peritoneal Folds
- The broad ligament encompasses the peritoneum reflecting off pelvic structures, creating a pathway from the posterior pelvic wall to the bladder.
Summary
- Structural integrity of the pelvis is maintained through a combination of ligaments, fascia, and connective tissues.
- Understanding these supports and their classifications is crucial for recognizing potential pelvic disorders and prolapse issues.
